It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us."

Is that going to be a great day, or what?

All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German.

As complex as all this sounds, it could turn out to be relatively simple.

India’s title triumph in the Under-19 cricket World Cup at the Bay Oval in New Zealand seemed inevitable. Prithvi Shaw’s boys, astutely coached by Rahul Dravid, maintained an unbeaten record through their three-week sojourn. The rousing campaign commenced with a 100-run win against Australia on January 14; in subsequent games, Papua New Guinea, Zimbabwe, Bangladesh and Pakistan were all emphatically defeated. There were no big-game nerves and even in the much- hyped semifinal against Pakistan, India pocketed a facile 203-run victory. In the summit clash against Australia, Shaw’s boys followed their template of dominance.

Australia was bowled out for 216 and India cruised home in 38.5 overs with eight wickets to spare, and enjoyed the added lustre of opener Manjot Kalra’s unbeaten 101. Through the tournament India found diverse heroes. Fittingly, its batting troika of Shaw, Kalra and Shubman Gill, along with seamer Kamlesh Nagarkoti and spinner Anukul Roy, found a berth in the International Cricket Council’s Under-19 World Cup team, essentially a tribute to the best players on view in the championship. Cricketing excellence allied with the resultant celebrity status, especially during the teenage years, can be a double-edged sword and it helped that in the dressing room there was the calming presence of Dravid. As the ecstatic players leapt and photo-bombed after clinching the trophy, Dravid cut through the hype and said that this win should not be the team’s defining memory as each individual cricketer has much more to achieve in his career. Dravid has a point. India has won the Under-19 World Cup on four occasions, including the previous golden runs in 2000, 2008 and 2012. From among these champion sides, only a few graduated to the big stage. Yuvraj Singh and Virat Kohli came through the under-19 ranks and managed to carve a niche for themselves, but Unmukt Chand, who led the team to the Cup in 2012, and then featured in a soft drink advertisement besides writing a book, has been unable to make it to the Indian senior team.
